Hi... Lavender oil is often used to ease headaches/ migraines.... Either by inhaling for at least 15 minutes... Or putting a small ammount directly on forehead/temples... Lavender oil is one of the very few oils that can be used directly on skin, in small ammounts. However, in order for it to work properly, ideally you do actually have to like the smell of it. I personally don't like it, so therefore have never used it in this way, but it is meant to be quite effective..... Also I would always advise, that if any condition comes on suddenly, and persists, to check with doctor first for any further possible medical issues.
